Re: DV6646us harddrive upgrade

You have to disassemble the old drive a bit. It is in a caddy held in with 4 screws at the corners and then there is an adapter that slips over the SATA connectors so they fit to the laptop inside. You have to take the old drive out of the metal frame (caddy) and remove the connector and then put that on the new drive and rebolt the new drive in the caddy the same way the old one came out. I assure you there is a hard drive physically identical to your new one inside that laptop if you strip away the extra parts. You picked a good drive there by the way
